SHORTER, LIGHTER, MORE ECONOMICAL
Even technically matured products such as pneu-matic clamps can always be optimized in details. One example for this is the new universal clamp of the mechanical engineering specialist TÜNKERS. It saves up to 30 % air pressure with performance data remaining unchanged, shows a significant-ly optimized design and sets new standards in weight category.
The universal clamp – based on an intelligent and compact design – is the perfect alternative to the vario clamp providing the same performance data:
· Equal clamping force · Equal retention force · Equal connection dimensions · Equal load cycles (3 million) · Proven, continuous angle adjustment
from 5 – 135°

It saves up to 30 % air pressure with performance data remaining unchanged, shows a significant-ly optimized design and sets new standards in weight category.
This is possible due to a power-optimized knee-le-ver mechanism having the effect that for size 50 clamps now sizes 40 cylinders are used and for size 63 clamps size 50 cylinders. The overall length of the U-shaped clamp is reduced by 25 mm and creates additional space in the fixture.

Both air connections are space-optimized and ar-ranged in the front and rear in the cylinder base. The U-shaped clamp offers a fully enclosed alu-minium housing, a slot for mounting the sensing cartridge is not required. The sensing satellites are not mounted on a carrier, but tightly and safely in-tegrated in the clamp housing in a shock-resistant arrangement. The adapter plate with plug contact is also tightly connected with the housing. Optio-nally the housing can be provided with a resistant to welding debris coating.

ANYBODY CAN CLAMP – BUT NOT THE INTELLIGENT WAY!
The electric series EK of TÜNKERS with conven-tional 24 V DC motors from large-scale producti-on has proven its worth as a smart alternative to knee-lever clamps with pneumatic drive.
The step-change in development to completely fle-xible fixture building is accomplished by the intel-ligent electric clamp of TÜNKERS. It enables free programming of speed and angle for each clamp. Moreover feedback of the actual clamping force is feasible.

ANYBODY CAN CLAMP – BUT NOT THE INTELLIGENT WAY!
Knee-lever clamps with pneumatic drive have es-tablished worldwide in body-in-white for decades construction. Studies show, however, that from a safety perspective air pressure is no longer in keeping with the times.
The electric series EK of TÜNKERS with conven-tional 24 V DC motors from large-scale producti-on is a smart alternative. This opens the way for body-in-white construction free from compressed air. The EK series offers clear energy savings and reduces operating costs by factor 15. The product series enables controlled moving of the clamp.

1KG LIGHTWEIGHT GRIPPER FOR CLAMPING AT THE ROBOT GRIPPER
Especially when taking account of new robot ge-nerations with high acceleration values, the gripper structure needs to be protected. Vibrations are the death of a gripper.
This is where the new ultra-lightweight series of TÜNKERS starts. Gripper clamp, knee-lever clamp and retract pins – all devices that make the heart of a gripper designer beat faster are available with an optimized interference contour and in particular for robot gripper applications.

1KG LIGHTWEIGHT GRIPPER FOR CLAMPING AT THE ROBOT GRIPPER
It is quite astonishing to see which delicate equip-ment at robot grippers holds car body parts. This results in grippers with a total weight of clearly more than 100 kg with moving components with weights of nearly 10 kg.
Especially when taking account of new robot ge-nerations with high acceleration values the gripper structure needs to be protected. Vibrations are the death of a gripper. This is where the new ultra-light-weight series of TÜNKERS starts. Gripper clamp, knee-lever clamp and retract pins – all devices that make the heart of a gripper designer beat faster are available with an optimized interference cont-our and in particular for robot gripper applications.
The new small series provides you with a product programme, which is particularly designed for ro-bot grippers. The new size 30 replaces normal si-zes 50 and 40 being actually oversized. Instead of 2 – 4 kg the new products are in a weight range of 1 – 1,5 kg
All advantages at a glance:
· New weight reserve in gripper design · Reduction of robot oversizing · Reduction of interference contour during grip-
per immersion into the fixture · Optimization of the centre of gravity of the enti-
re system by weight reduction of the externally located arms of the fixture.

E-CLINCHING UNIT WITH INTELLIGENT PROCESS MONITORING
The new E-clinching unit designed by TÜNKERS works with a particular servo-control to make set values reproducible and to achieve sustainable and process-reliable joint connections.
The parameters of force/torque and the final joi-ning position can be defined and adjusted very precisely via the adapted process monitoring. To achieve reproducible joining a very rigid and also lightweight design of the FEM optimized C-frame is crucial, it prevents axis offset between the stam-ping tool and the template when the frame is bent open by the process forces.

E-CLINCHZANGE MIT INTELLIGENTER PROZESSÜBERWACHUNG
Clinching is a joining process, which has proven its worth in particular in car body manufacturing for joining processes of different mating plates or aluminium connections.
A very precise control of force/displacement of the punching tool and joining template is essential for sustainable and process-reliable joint connections so that the set values - the so-called residual wall - of a few tenths of a millimeter are achieved.
For this reason the new E-clinching unit designed by TÜNKERS works with a particular servo-con-trol. The parameters of force/torque and the final joining position can be defined and adjusted very precisely via the adapted process monitoring. To achieve reproducible joining a very rigid and also lightweight design of the FEM optimized C-frame is crucial, it prevents axis offset between the stam-ping tool and the template when the frame is bent open by the process forces.
The newly developed power unit has a planetary roll spindle, running in oil and therefore maintenan-ce-free, due to its special construction its design can be extremely narrow.
The movable, open template of the TÜNKERS E-clinching unit offers higher process reliability with the following advantages:
· Low risk of pollution due to open template design. Humidity, oil or component coatings do not result in direct loss of quality (pressure stasis!!)
· Flexible with plate thickness variations due to open, laterally yielding design
· Joining of different mating plates with one tool kit
· Low joining forces (./.20%), as material can flow in the direction of yielding lamellae
· Lower stripper forces, as template stripper is replaced by a simple stripper design on punch side

DOUBLE PERFORMANCE WITH DOUBLE ROLLER
Conventional rotary indexing tables are driven by an electric gear motor with a so-called barrel cam, which moves the rotary table by a roller bolt. The intermeshing roller bolts limit the maximum torque transferable to the rotary tables.
The new EXPERT-TÜNKERS high-performance rotary table uses two „dual principle“ patented rollers, arranged in parallel and driving the rotary table.
In practice, duplicate performance values can be achieved with nearly unchanged dimensions of the rotary table.

The new EXPERT-TÜNKERS high-performance ro-tary table uses two „dual principle“ patented rollers arranged in parallel and driving the rotary table.
In practice, duplicate performance values can be achieved with nearly unchanged dimensions of the rotary table. Another clear advantage is that the rotary table is evenly driven from both sides and therefore without one-sided bearing load, which occurs with conventional rotary tables.
In conjunction with the drive reduction gear inte-grated in the housing an extremely compact drive system is created, which is particularly suited for high performance applications in car body cons-truction.
Overview of the advantages of the double roller ro-tary table EDC 960 of EXPERT-TÜNKERS:
· Optimized dynamics - reduction of cycle times possible
· Higher mass moment of inertia - optimized for complex client superstructures
· Optimized power transfer - even radial bearing load
· Cost-effective and compact - only one servo motor as drive
· Maintenance-friendly - drive easily detachable

WELDING AT DOORS AND FLAPS
Spot welding is used to fix parts to bonded and se-amed components, primarily to body panels, e.g. doors and flaps in the field of body-in-white.
The TÜNKERS welding clamp equipped with a special ground electrode offers a new method to bring in these spot welding points.
In addition to simple and robust technology the electrode arm, which can be opened to 90° offers advantages with regard to accessibility in the fix-ture.

WELDING AT DOORS AND FLAPS
Spot welding is used to fix parts to bonded and se-amed components, primarily to body panels, e.g. doors and flaps in the field of body-in-white. Spot welding can be directly performed in the seam. Due to released welding heat the subsequent ad-hesive gelling process may be dropped.
By reducing the electrode contact surface the wel-ding parameters can be optimized to the extent that only the inner plates are welded to each other and therefore no welding residues occur at the ou-ter shell.
The TÜNKERS welding clamp equipped with a special ground electrode offers a new method to bring in these spot welding points.

PUNCHING - EVEN IF SPACE IS TIGHT!
As a rule, drilling additional holes in body-in-white is not a Herculean task. But things become more difficult as soon as a number of holes have to be drilled in extremely narrow spaces and preferably in one operation.
The very narrow TÜNKERS C-frame with a flat oval multi-force cylinder has proven to be an advantage enabling the entire punching fixture to be designed in battery alignment.

The very narrow TÜNKERS C-frame with a flat oval multi-force cylinder has proven to be an advantage enabling the entire punching fixture to be designed in battery alignment.
An example of automobile manufacture demons-trates clearly how the C-frame units can be used: for the subsequent attachment of a side skirt 10 additional holes with a 9 mm diameter had to be punched at the left and right car side on the skirt.
In addition to restricted space conditions - the cur-ved surfaces, different hole distances and the pla-cement of the holes at different levels were specific challenges of this task.
An optimum solution for this task was provided by six space-saving battery-arrangements of C-fra-mes with multi-force cylinders in flat design. These units consisted of four C-frames with two punching tools with contour templates and two C-frames with one punching tool with contour template. As the side skirt could subsequently cover the holes, punching could be performed from inside to out-side.

CONFIGURATOR ACCELERATES DELIVERY TIMES
Accumulating conveyors are complex. Also due to this fact there was not yet a universal CAD model available showing the entire range of all possible design version.
This is just what the new TÜNKERS Configurator AFS-CONCAD offers: all possible variations with regard to length, width, loading position and stop stations are technically described with their mutual dependencies to each other.

This is just what the new TÜNKERS Configurator AFS-CONCAD offers: all possible variations with regard to length, width, loading position and stop stations are technically described with their mutual dependencies on each other.
The configurator creates the constructive design of a complex conveyor belt not only more quickly, but it also enables the end-user and plant designer to create his own models or to adapt them to his installation situation. A total of 8 basic models is available.
With a user manual all required parameters are de-fined and in this manner the optimized accumu-lating conveyor for your individual requirements is configured. Designs exceeding the predescribed models are separately planned by TÜNKERS.
The intended target of the TÜNKERS configurator is to increase design speed and hence to reduce in particular the required coordination loops with the end-user. The approval process will be simpler and quicker, submission takes place at the touch of a button.

DOUBLE-LOCKING LINEAR UNIT
In the event that a version with both end position locked is to be built, further components (brake, clamp, shot pin, cylinder) are additionally required and must also be separately controlled. Tünkers now offers a new linear unit, which is backlash-free locked in both positions and based on the paten-ted dual knee-lever mechanism.
The functional principle:
· As with the knee-lever clamp, the piston rod of the cylinder does not act directly, but acts on the skid via a knee-lever joint.
· In the end position the joint moves „past the dead centre“ – the position is mechanically locked, backlash-free and therefore secured in the event of a pressure drop.
· The joint is designed as a double angle and therefore locked in both positions.

In the event that a version with both end position locked is to be built, further components (brake, clamp, shot pin, cylinder) are additionally required and must also be separately controlled. Tünkers now offers a new linear unit, which is backlash-free locked in both positions based on the patented dual knee-lever mechanism.
Many linear units need to be mechanically locked in both end positions, e.g. because type-specifi-cally two working positions are approached. What at first glance does not seem to be very deman-ding, is coupled with relatively great effort in its technical design requiring additional shot pins or locking elements.
This should be much easier with the patented TÜNKERS linear unit LEV 100. The drive cylinder is not directly controlled on the skid, but control-led via a dual knee-lever - backlash-free locked in both positions.
The functional principle:
· As with the knee-lever clamp, the piston rod of the cylinder does not act directly, but acts on the skid via a knee-lever joint.
· In the end position the joint moves „past the dead centre“ – the position is mechanically locked, backlash-free and therefore secured in the event of a pressure drop.
· The joint is designed as a double angle and therefore locked in both positions.
For the cases where the total stroke is to be adjus-ted or corrected on-site, Tünkers Maschinenbau GmbH provides the LEV unit also with vario lift.

ROTARY CHANGER IN VERY FLAT DESIGN
Component supply in transport containers directly in the robot cell on-site has established as a stan-dard in body-in-white. To ensure constant availabi-lity, at least two container spaces need to be pro-vided at the cell - following the principle: full box / empty box.
For inward and outward transfer mostly container changing systems operating overhead are used.

The new flat rotary table TXR is the core cell of the TÜNKERS Rotary Changer. It reduces compo-nents required for a rotary indexing table to a mi-nimum: base plate, bearing, toothed belt and gear motor. The result of this design is a simple, robust and simultaneously flat design.
The mechanical separation of motor and rotary ta-ble allows an optimized construction with external arrangement of the drive. For this reason the TXR rotary tables are particularly suitable for low-floor drive to rotate large and widely projecting loads, e.g. rotary container changers.
The system can be implemented as a rotary chan-ger with 2 or 3 containers.
